Answer 3

Okay, what do you think we do first at least?

Answer 5

This question is different than all the othe ones Ive been doing

Answer 6

Okay, so if we do .50 x 1.20 we get 0.6. That equals .60. Which can equal 60 cents. On the right page with me so far?

Answer 7

yes, writing it in my notebook

Answer 8

Alright. Now what do we do?

Answer 9

2.00 x .30=.6 & 3.50 x .20= .7

Answer 10

Answer 11

Answer 13

Answer 14

Yes, indeed. Sorry, you didn't say the milkshake step. But you got the calculations. :) 0.6+0.6+0.7=60 cents plus 60 cents plus 70 cents. Equals 190=$1.90
